Cause

This issue is caused by corruption in the Data Aggregator cache in the /opt/IMDataAggregator/apache-karaf-2.4.3/data/cache directory. 

Environment

Release : 20.2

Component : IM Discovery

Resolution

This will correct the issue. 

1. Stop the DA 

service dadaemon stop 

2. Move the data directory. 

mv /opt/IMDataAggregator/apache-karaf-2.4.3/data /opt/IMDataAggregator/apache-karaf-2.4.3/data.old 

3. Restart the DA 

service dadaemon start
